As stared.; one yel 'the purposes of the invention, .is "to provide. ineens for producing eyir vcurrents in the cooling elmrnoerto promote elle efficient cooling effect recompile-ned by the conrei'ners nollingthe iro-zen liqui.

This means, in he presenr instance of the invention, comprises e, pair bellows l5 nl; opposite ende of the chamber. The bellows here movable necks Je? morided With fingers 49 progieeting into 5l at ends of the containers adje ent 'ico the, bellow-s. The lower ends of the bellows ere open 'to vdirect air lcurrents downward in "1 the direction of the arrows {F.ig. 3) 'when the bellows fire collapsed. l

The mfoions which truck body is Sul)- jecteel to during rravel of ne motor truelr,

`Will cause the end containers. lo swing on'` their nengers and. ,this motionwill ne transmrl'ed rlirongh ine iin-gers 49 *co @he booke of the bellows, end rhereby produce the downwardly clireeed au' currents; which will result in e circulation of elle eir in the coolingyehamoer Whieh will cause the air cooled by ehe eonbeiners holding elle frozen liquid 'io paso riownward an eiii! ifm lost their substantial cooling effect, they may be removed from the cooling chamber and be returned to Ithe freezing room for the purpose of again freezing the liquid therein.

Preferably, two sets of containers are provided for each truck, one set to be in the freezing chamber in readiness to be substituted fbr the set in the truck body when required. Thus, the refrigeration or cooling effect in the truck body may be continued indefinitely or renewed from time` to time as required.

The number of containers employed may vary according to the size of the cooling chamber and the vdegree of refrigeration desired. y

The truck body may also be constructed to provide a chamber 55 adapted toyreceive broken 'iceI and a chamber 57 `adapted to receive salt. The ice chamber may have doors 59 and 61 at the tops thereof through which the ice and salt may be introduced into the chambers. VAt one side of the body is a disch-arge door 63 mounted in guides 65, said door being provided with a handle 67 and a latch 69. This door may be opened to enable :broken ice and salt to be taken from the chambers 55 and 57 for'the purpose of. packing the ice cream cans in tubs to keep the cans cold. A

It will be understood that the invention is not limited to the specific embodiment shown, and that various deviations may be made 4therefrom without departing from the spiritfand scope of the 4appended claims.

Whatis claimed is 1. Refrigeration apparatus comprising, in combination, a cooling chamber, a container movably mounted therein and adapted. to hold a frozen liquid, and a bellows operated by movements of said container for producing air currents in said chamber for promoting the cooling effect of said container.

2. Refrigeration apparatus comprising, in combination, a cooling chamber, containers movably mounted therein and adapted to hold a frozen liquid, and bellows operated by movements of said containers for producing air currents in said chamber for promoting the cooling effect of said containers.

3. The combination of a vehicle having a body provided with a cooling chamber, a bellows mounted in said chamber, a container in said chamber adapted to hold a frozen liquid and susceptible of swinging movements occasioned by motion of the body when travelling, and means to connect the container with the bellows for operating the latter from the former.

4. The combination of a vehicle having a body provided with -a cooling chamber, a plurality of containers therein, at least one of said containers beingsusceptibleof movements during travel of the vehicle, and a bellows operated by said movements for producing air currents in the 'cooling cham- 5. The combination of a vehicle having a body provided with a cooling chamber, supports at the to of thechamber, a plurality of containers etachably connected to said supports and each adapted to hold a frozen liquid, bellows at opposite ends of the chamber connected to the containers adjacent thereto in order that swingingmovements of said containers occasioned during travel of the vehicle may operate the `bellows to produce air currents in the chamber, and means connecting the containers intermediate the bellows operating containers to prevent them from swinging.

'6. The combination of a vehicle having a body provided with a cooling chamber, a plurality of containers mounted therein, each adapted to hold a frozen liquid, and means detachably'to connect the containers with one another permitting their individual introduction into the chamber and removal therefrom.

7.. The combination of a vehicle having a body provided with a cooling chamber, a series of supports extendin transversely of the body at the top of the chamber and distributed at intervals throughout the length of the chamber, and containers having hooks adapted to be removably connected to said supports, each of said con-A tainers being adapted to hold a frozen liquid, said body being provided with a door through which the containers may be introduced into said chamber and removed therefrom.

8. The combination of a vehicle body provided with a cooling chamber, supports secured to the top of the' chamber and distributed at short intervals throughout the length of the top, anda plurality of frozen liquid holding containers having hooks at the upper ends thereof connected to said supports, a pair of the containers being supported on each support, and means connecting the containers to prevent them from swinging against each other.

9. The combination of a vehicle body provided with a cooling chamber, a series of supports secured to the top of the chamber and distributed at short intervals along the length thereof, pairs of frozen liquid holding containers connected to said supports in tandem relation, ears projecting from adjacent ends ofleach pair of the containers,

and a holding strip detachably secured tol said ears for reventing the containers from swlnging agamst each other.
